The current VXGI implementation should be theoretically more efficient and to the same quality than SVOGI, simply because it uses cascaded 3D textures which are sampled directly by the cone tracing. The sampling of octrees was quite intensive by comparison. The reason why SVOGI was able to run on a gtx680 was because a lot of its meshes had to be static, whereas VXGI can be fully dynamic. The use of direct 3D textures instead of octrees is the only difference between the two techniques and everything that was done in SVOGI can be done in VXGI.

I think the complaint is that VXGI won’t run on anything but Nvidia cards, whereas SVOGI was brand agnostic.
